App Card is a great way to better represent mobile applications on Twitter and to drive installs. We designed the App Card to allow for a name, description and icon, and also to highlight attributes such as the rating and the price. This will require adding some new markup tags to your pages, which we will cover in this document. This Card type is currently only available on the iOS and Android mobile clients. It is not yet available on web or mobile web.
This Card is unique, as we use each of the respective app stores to proxy the pertinent Card data. The App Card is great for things like your homepage, or your /about page. All you need to do is specify the Card type, and each of the corresponding App IDs to the respective app stores so that we can proxy the rest for you (# of reviews, # of stars for the app, etc.). You also can optionally specify a more concise description of your app.
Twitter auto-creates App Cards for Tweets which contain a link to either the App Store or Google Play. This means that you can create an App Card experience just by sharing links directly to the download page for your application.
